Don't know whats going on this month

Ever since I've been taking my temperature, it would rise anywhere between 14 to 17 days. My period is always between 28 to 31 days. This month i am on day 23 and my temp has not gone up. On day 18 i started noticing some e***hite and i had it on day 18, 19, 20, and 21. Then on day 22 i had a creamy but no e***hite discharge. This morning i was a little dryer. Haven't been back to the bathroom to check. But my temp was 97.4 so it is still very low. Yesterday it was 97.3. I don't know whats going on with me. I'm getting a little worried that i won't be able to have anymore children. I have a 6 year old and my other son died at birth last year. My arms ache for another child since I lost my baby.
